Question

A stock solution of hno3 is prepared and found to contain 13.5 m of hno3. if 25.0 ml of the stock solution is diluted to a final volume of 0.500 l, the concentration of the diluted solution is __________ m.

Answer 1

so 0.5 x 100 / 25 = 20 this is the dilution factor

So now divide the moles by the factor: 13.5/20 = 0.675M
